WEE-DELVERING ATTACHMENT FOR -AUTOEOBIWE TRUCKS OR Continuation of application Serial No. 576,309, led

isaa. serial all I1li/l om -iz may concern Be it known that l, Luo Hnrnrnrr, a citizen ot the United States, residing at yMuskogee, in the county ot' Muskogee and State of Oklahoma, have invented new and useful Improvements in Power-Delivering Attachments for Automobile Trucks or Tractors, of which the following is a specification.

This invention relates to power deliv ering attachments-tor automobile trucks or tractors, and the present application is a continuation of the alloyed application, Serial No. 576,309, tiled by nie on July 20, 1922.

The object is to provide mechanism which may be readily incorporated in the structure of trucks, tractors or similar machines for the purpose ot' delivering the power generated b v the tractor engine and utilizing the same tor other purposes while the tractor is standing still and not engaged in pulling operations.

Another object is to provide such means for the purposes specified, which may be applied or attached to the tractor with a minimum amount of change in the latter, and which may be readily detached from the tractor if desired, the additional mechanism, however, being so designed as to remain on the tractor it preferred and not to interfere with 'the operation ot the same' while en.- gaged in pulling. 5

A further object is to provide an attachment for tractors whereby the power from the engine thereof may be directed to the traction wheels tor the ordinary use of the same, or may, at the will of the operator, be disconnected therefrom to allow the tractor to stand still, and the said power directed to the improved mechanism, located out of the way ot the operator, for the purpose of hoisting, hau-ling or driving belts, etc., the controlling means for the mechanism being within easy reach of the operator or driver, so that such changing or shitting may he effected instantly.

A further object is to provide means for controlling the mechanism when being used .for hoisting loads so that the sai-d mechanis-m may be disconnected from the engine] power and the said load be lowered as desired by brake mechanism includedV in .the attachment..

A. still further Objectis to incorporate, in

July 2o. 1922. No. eresia.

the present application, improved' teaturesA in the power transmitting gearing between the ditl'erential gearing in the rear aule or the truck or tractor and the winding drum shaft, to constitute means whereby the said drum maybe driven in either direction at different rates ot speed to wind up a rope or cable, such rate being optional with the operator and permitting the cable to unwind from the drum underthe control ot said operator, when it is desired to lower the load or to pay out the cable.

A full and complete understanding of the invention may be obtained 'from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification; it being understood that whilev the drawings show a practica-l form of the invention, the latter isnot confined to strict conformity with the showing thereof, hut may be changed or modified, so long as such changes or modifications mark no material departure from the salient features of the invention, as specifically pointed out in the appended claims.

ln the drawings, in which similar refererence characters designate corresponding' parts throughout the several figures:

Fig. l is a horizontal sectional view through the rear axle structure of an ordinary tractor and showing the improvements att-ached thereto.

Fig. 2 is a side elevation of the rear end of the tractor, showing the location of t`l e attachment, the rear tractor wheels being omitted.

Fig. 3 is a vertical section through the mechanism, taken longitudinally of thetnactor. y

Fig. 4 is a detail sectional view/showing the manner ot closing the openinglin the rear portion of the dierential housing when the attachment is removed. 'i ln oil Fields and other similar places where tractorsare in. general use for the purpose of pulling or hauling loads or for the cultivation of the ground onY a large scale, a great demand has been created for means to be used in connection with 'the tractor whereby the power from the engine may he utilized for hoisting purposes, as, torinstance, the raising orlowering ot rods, tubing or casing Vintotor out of oil wellsv andy or Uther sirnilar purposes. Such means inustnecessarily be small and compact and so located or applied to the tractor as not to interfere with the freedom of operation et the latter in its coininonuse, and Inustbe readily handled or controlled by the driver while sitting in his usual seat or capable of control troni the ground..

'l he improvements disclosed herein are designed to tuliill this demand, and are so iron-y. structed as to require only a small. amount of; change in the structure of the tractor in or-,` der to apply the saine in position, and the saine may be readily removed from the tractor and the latter lett in its normal condition when desired.

lllhile the drawing?r shows the improvements applied to a tractor of a well known form, the invention may be used in connection with an automobile or truck with equal advantage as Awill become apparent.

lieterring to the drawings, l indicates the ear portion of the transmission housing which in the forni of a tubular casing ter- Initiating in a circular ring, the axis of which is at right angles to the axis of the part 1, the latter constituting the trunk or back of the tractor. .Secured to the opposed edges or the circuhnnring are conical or tapering rear axle housings 2 having integral flanges which are secured to the said ring' by bolts 3. rThe axle housings are provided at their inner, enlarged ends with circularseats 4 into which are adapted to be placed ballhearing` rings 5. the outer ends of the hous-. ings being similarly provided with seats for the recept-ion of roller-bearing cages 6 and the intermediate. portions of the said housings being' provided with similar roller bearings 7, all of which may be ol' the usual forro construction. Mounted in the roller bearings 6 and 7, at

each side of the machine are Aseparate axles to the outer, exposed ends of' each of which are secured, 1n the usual manner, traction .wheels 9 which may be of any desired form,

the said abiles being;r free to rotate independently of each other. The inner ends of the axles or spindles 8 extend inwardly beyond the roller bearings 7, and are provided with longitudinally disposed series of slots or grooves 10 to provide teeth for engagement with corresponding teeth provided in slidable clutch rings l1 located inthe cavities 12 provided in the inner, enlarged ends of the tapering housings 2. v

Mounted and supported within the ballbearing rings are short shafts or axles 13, havingr their outer ends in abutting relation to the inner ends of the separate axles 8 andv their inner ends abutting against each other. at the longitudinal center line of the tractor. tht said outer ends beiner providedwith lone'itudinal grooves lil matchingr the grooves` i0 and. adapted to receive the slidable ring 11, when the latter is shifted, and to be locked thereby to the axles 8, said ring beings,r lnoved so that both ends of 'the shafts or axles'will be covered thereby and caused to rotate in unison.

The slidable rings are' each provided with an annular channel "for the reception of a yoke 16 provided at the inner ends of operating levers 17 extending forwardly through openings 18 provided in the front walls of the tapering housings 2, the said levers being provided w'th vertically disposed pivot pins 19 suitably mounted in bearings 20 to permit the levers to be swungnr inwardly and outwardly for causing the engagement or dsengageinent ot' the rings l1 with the adjacent ends of the abutting axles 8 and 13, respectively. pressed detente 2G, adapted to engage correspondingr notches in the bearings 20, are employed to hold the levers 17 in either adjusted position. lVhile the levers are shown as extending forwardly, the same may extend in any other radial direction, but this posltion locates them in a convenient place to be operated by the driver. and it will be seen that they may be extended or otherwise connected to-be located elsewhere. it desired.

The inner ends of the short axles or shafts 3 are provided with grooves 21 which receive correspondingr teeth formed in spaced, opposed differential gears 22, o't the beveled type, which lock the same t e said gears with their respective axles to turn together at all times in either direction. Mounted on the inner reduced ends of the short axles 13. which abut against each other, is a spider ring'f which is free to rotate thereon.,I and the said ring is provided with a plurality of outstanding stud shafts 24 upon each of which is,loosely mounted a beveled. differential pinion 25 meshing; on either side with the teeth of the gears 22, and adapted to act therewith in the manner of the well known differential gearing of' machines of this class, in order to allow one tractor wheel to turn independently of the other for turning corners,'etc.

rlhe differential gears and pinions' are housed within the two housing members :26 which are hollow and semi-spherical in shape. the two halves bein;lr provided with coactina bearing soclfets Q7 which are adapted to lit together and receive the outer ends of the pinion shafts 24. and are provided at theirl outer ends with cvlindrical collars or bearings :28 for the reception of the inter.

mediate portions of the short axles 13 and abutting' against the innerfliaces of the ball hearing rings 5.

The housing members 96 are further Drovided with integral. circular plates or discs 29 'in spaced relation to each other, and provided'with annular offsets 30 to constitute circumferential shoulders for receiving a thereon and cause Suitable springies . ing 38 incassa worin gear ring 31 and properly position theY saine therebetween the housing members and the worm gear being he'ld together by means of a series of bolts 32.

The worin gear 3l is engaged on its lower side by a worin 33 mounted on the extension et the engine 'shaft 34, the rear end of said extension being suitably mounted in an antiriction bearing 35 located at the rear end of the casing and adapted to be covered by a draw bar cap 36 having means for connection. with the iplement or load to be drawn by the tractor when the saine is in such use. n

One oi' the discs 29 is provided with an annular, outstanding, peripheral dange having external gear teeth extending entirely around the same Aand constituting a gear wheel 37 of lesser diameter 'than the diameter o-' the worm wheel 31. The opposite disc 29 is extended beyond the periphery of the worin wheel 3l and is provided with an annniar iiange having teeth and constituting a gear 'wheel 37a of greater diameter than the worrn wheel and the relative diameters of these wheels rnay vary.

The circular, enclosing portion l of the housing l., which eneircles the major portion of the 'gears described, is provided in its upper, rear portion with a rectangular openthrouh which is permitted the meshing et spacedgears 39 and. 39a with the gears 37 and 37, the said gears 39 and 39a being carried in a housing '40 composed of two equal halves, the lower member of which is provided with attaching danges 4l adapted 'to receive bolts 42 for securing the housing et() in position over the o ening 38 the angle between the centers of the two hous- .ings being substantially at fifteen degrees with respect to a horizontal line.

The gear 39 is of considerably greater diameter than the gear 39, and is adapted to engage with 'the teeth of the relatively small gear 37 carried by the diii'erential gearing when the same is shifted longitudinally of its axis, while the said gear 3Cn is of a diameter to mesh with the teeth of the gear 37a when such longitudinal shitting movement is imparted simultaneously to the 39 and 39-, in a manner to bedesoril y housing 40, which has its two members secured together by lange and bolt const .lion 43, may readily have its outer member removed for exposing the othe housing and to aicord access ."#echanisni contained therein. The s of the two n'xenibere comprising `4G are provided with coactine;

hearinss thereception of the shaft 44, which i. 'i ded with a series ot lonnxtun dinaiiy dispou teeth extending between the inner faces et tneiside walls oi the housing 40 and to inteisncsh teethcarried by the gears 39 and 39 which are spaced apart by spacing sleeves 46 having end tlenges 46 between the inner pair of -Which is clamped a disc 47 of less diameter than the adjacent anges 46, the several members being held together by a series of the cover member of the housing and pivoted` between ears 52 for a swinging movement transversely of the longitudinal axis of the tractor to slide the gear 39 or 39a into or out of engagement with the gears 37 or 37a. The operating lever 450 may be moved in either direction to disengage the gears, and coacts with'a toothed sector 53 located below the lever and adapted to be engaged by a spring-pressed pawl operated by van ordinary latch lever 54 so that the. said lever rinaty be locked either-to the right or the The width of the `housing 40 is suiicient to permit of three positions of the gears, as will be seen by reference to Fig. il of the drawings, that is, one position when the large gear 39 is in mesh, as shown in full lines; another intermediate position when both gears are in neutral orout of gear, as indicated in dotted lines; and a third position as' when the smaller gear 39E is in mesh, not shown. llt will be seen that when the gears 372L and 39 are in engagement, a greater rate of speed will be imparted to the winding shaft 44 than when the gears 37 and 39 are in mesh, and that the number of speeds supplied through the mediurnof the transmission gearingl of the tractor (not shown) will be doubled in the winding shaft. in either direction.

a rearwardly directed bracket 55 is bolted or otherwise secured to the reduced extended portion of the adjacent axle housing. the said bracket extending upwardly at an angle ot substantially fifteen degrees, and is provided with a terminal bearing 5G to receive the end Adjacent to the righthand tractor wheel 9 I of the shaft 44 which is extended to that y bolted to the tapering portion of the axle housing and a heit pulley 6l is keyed on the end of the shaft beyond the hracltet 60 for the purpose ot driving' a heit for any desired purpose.

Between the bracket 60 and the adjacent side Wall oi the housing 40, it flanged hralie wheel 6l is keyed or otherwise secured to the shalt 44, and a brake hand G3 is fitted hetween the flanges of said Wheel and has one end suitably secured to a convenient part of the housing 1while the other end of said hand is secured to a crank 64 of an actuating,T shaft having suitable hearings 66 formed in the flange of 'the axle housing 2 and the bracket of), respectively, said shaft 65 being; parallel with the rear axles and having an operating lever 67 secured to the extended end thereoiE for the purpose of applying the brake hand when it is desired to control the retrograde movement of the shaft ed when the gear Wheels 39 and 39 are out of engage ment with the gear Wheels 37 and 3?, respectively.

l/Vhen it is desired to use the tractor as a hoisting device, it is only necessary to swing' and loci; the levers 1'? in the position shown in Fig. l oi"- the drawings, when the toothed collars il are removed from eng-agement with the short axles 13 and the main axles 8 are idle and the tractor Wheels 9 stationary. Assumingy that the rear lever 50 is moved into the position shown with the. 'gears 39 meshingr with the gears 37, the engine clutch (not shown) may then be shifted to impart motion to the shaft extension 34 when power will he imparted through the worin 31 and associated parte, through the wheel 37 and 39 to the shaft 44 when the drum will "oe revolved in the desired manner, and at a relatively slow rate of speed. When a greater speed is desired, the Wheels lB7a and 39a are first shifted into mesh. When the load is lifted to the desired elevation and it is desired tolowcr the same, the power may he eut oil at the engine clutch, and the lever 50 stvungto engagethe latch or pawl with the central notch of the sector 53 ,which moves the wheels 39 and 39a to the neutral position, and hy hearingr on the brake lever 67, the unwinding movement of the drum may he easily controlled. By removing,r the brackets 55 and 60 together with the members comprising the housing 40 and the parts carried thereby, the entire hoistingr attachment may he removed from the tractor, the levers 17 remaining in position and the opening 38 being covered hy a. curved plate 68 held in position by bolts 69, as shown in Fig.` 4.

From the foregoing, yit Will he seen that a simple attachment for traetors, trucks, automobiles or the like has heen provided which may be installed in position Without materially altering the structure oi the tractor,

insonne and that simple and eective controlling means Within easy reachof the driver or opcrater has been provided hy means of which the machine may he driven at different speeds. as a tractor or' es a hoisting machine, or both at the same time, as the clutch rings l1l may he lett in connected position with the short axles i3 and the machine made to move forwardly or rearwardly at the saine time the Winding drums are actuated.
